Just stumbled upon this on the GAME website:

Seems like a first release to me, and comes with a replica Bumblebee Camaro.
This version is due out on the 24th of June 2011 - I expect a solus version of the game will follow shortly after release. Still, this is worth getting if you're a Wii or big box collector
